BuildOnce tells you about things that happen in your workspaces — a render that failed, a teammate who joined, an invoice that didn't go through — through two channels: in-app (the bell and the notifications page) and email. There's no separate API for any of this; it's part of the regular dashboard session.

In-app inbox

The bell shows your unread count and stays live while you have the dashboard open — new notifications and read-state changes (including from another tab) arrive over a live connection, not polling. The notifications page lists every notification across all your workspaces, newest first, filterable by read state and category, with mark-read and mark-all-read actions.

Email

Not every notification sends an email — most stay in-app only. Email is reserved for things worth leaving the dashboard open for: billing issues, security events (a new API key, a password change), a failed render or template import, a social post that failed to publish, and accepted invitations.

Preferences

Each notification type can be switched on or off independently for the in-app and email channels from Preferences. A handful of types are critical and can't be turned off on either channel — things you need to see even if you've muted everything else: a failed payment, running out of credits, your password changing, an API key being created or revoked, and a social connection expiring.

Unsubscribing from an email

Every non-critical notification email carries a one-click unsubscribe link (and the headers mail clients look for to show their own unsubscribe button). Using it switches off just that one notification type's email — it never touches the in-app channel, and never touches a critical type, since those can't be switched off at all.
